Technical Field

[0001] This utility model relates to the field of mine emergency rescue and demolition technology, specifically a cutting device for mine emergency rescue and demolition. Background Technology

[0002] During emergency rescue operations following a mine accident, various obstacles often need to be removed quickly. These obstacles can hinder the actions of rescue personnel, delay rescue time, and affect the progress of rescue work, thus requiring cutting equipment for removal.

[0003] Currently, some existing cutting devices used for emergency rescue and demolition in mines cannot quickly disassemble and assemble the cutting blades. The cutting tasks of these devices are usually high-intensity, and the cutting blades are prone to rapid wear due to friction, high temperature and other factors. This can lead to delays in rescue progress due to waiting for tool repair or equipment replacement, thus failing to meet the needs of users. Meanwhile, some existing cutting devices used for emergency rescue and demolition in mines cannot adjust their length, making it impossible to insert the cutting blade into narrow spaces for cutting work. This can lead to delays in rescue operations due to tool size issues. Furthermore, the inability to adjust the length prevents the device from cutting obstacles at heights, reducing its practicality.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-5 As shown, a cutting device for mine emergency rescue and demolition includes an adjustment box 1. An adjustment mechanism 6 is installed on one side of the inner cavity of the adjustment box 1, and a connecting plate 14 is installed on one side of the adjustment mechanism 6. A motor 3 is fixedly connected to the lower surface of the connecting plate 14. A disassembly and assembly mechanism 4 is installed at the output end of the motor 3. A cutting blade 5 is installed at the bottom of the disassembly and assembly mechanism 4. The adjustment mechanism 6 can drive the connecting plate 14, the motor 3, and the cutting blade 5 to move, and can adjust the length of the device. This allows the cutting blade 5 and the motor 3 to be directly inserted into narrow spaces for cutting, preventing the user from being unable to enter the space to perform cutting work. At the same time, it can be adjusted to the required length to cut obstacles at height, improving the practicality of the device. An installation port 10 is opened on the inner surface of the cutting blade 5. When the cutting blade 5 is damaged, the user can easily install the cutting blade 5 through the disassembly and assembly mechanism 4, reducing the time for replacing the cutting blade 5 and preventing the device from being stopped for too long, which would affect the rescue and meet the needs of the user.

[0016] The adjustment mechanism 6 includes a transmission rod 601 installed and connected to one side of the inner cavity of the adjustment box 1. A gear 602 is fixedly connected to the outer surface of the transmission rod 601. The gear 602 meshes with a toothed plate 603. A throttle 604 is fixedly connected to the other side of the transmission rod 601. Several limiting holes 11 are opened on the inner surface of the toothed plate 603. One side of the toothed plate 603 is fixedly connected to one side of the connecting plate 14. One side of the transmission rod 601 passes through the adjustment box 1 and is rotatably connected to the inner wall of its penetration point. Through the adjustment mechanism 6, the user rotates the throttle 604, which drives the transmission rod 601 and the gear 602 to rotate. The gear 602 drives the toothed plate 603 to move. The toothed plate 603 drives the connecting plate 14, the motor 3, and the cutting blade 5 to move. The length of the device can be adjusted, making it convenient to directly insert the cutting blade 5 and the motor 3 into narrow spaces for cutting. This prevents the user from being unable to enter the space to perform cutting work due to limited space. At the same time, it can be adjusted to the required length to cut obstacles at height, improving the practicality of the device.

[0017] The disassembly and assembly mechanism 4 includes a mounting plate 401 fixedly connected to the output end of the motor 3. The inner surface of the mounting plate 401 has a threaded hole 402, and a bolt 403 is threadedly connected to the inner surface of the mounting plate 401 through the threaded hole 402. With the disassembly and assembly mechanism 4, when the cutting disc 5 is damaged, the user can use a tool to turn the bolt 403 in the threaded hole 402 to remove the fixing of the cutting disc 5 and remove it. Then, a brand new cutting disc 5 is placed on the mounting plate 401 through the mounting port 10. The cutting disc 5 is fixed by turning the bolt 403 in the opposite direction in the threaded hole 402. The cutting disc 5 can be installed, which reduces the time for replacing the cutting disc 5 and prevents the device from stopping for too long, thus affecting the rescue. This meets the needs of the user. Moreover, the installation direction of the bolt 403 in the threaded hole 402 is opposite to the direction in which the motor 3 drives the cutting disc 5 to rotate, thereby preventing loosening.

[0018] A handle 2 is fixedly connected to the top of the adjustment box 1. The handle 2 allows the user to easily pick up and use the device. At the same time, the device structure is made of a lightweight material, which improves the portability of the device.

[0019] A slide rod 8 is slidably connected to the inner surface of one side of the adjusting box 1. A handle 7 is fixedly connected to one side of the slide rod 8. A spring 9 is fixedly connected to one side of the outer surface of the slide rod 8. The other side of the spring 9 is fixedly connected to one side of the inner cavity of the adjusting box 1. Before adjusting the length, the slide rod 8 is moved by pulling the handle 7 to release the limit on the toothed plate 603, and at the same time, pressure is applied to the spring 9. When the adjustment is completed, the pressure on the spring 9 is released, and the elasticity of the spring 9 drives the slide rod 8 to be inserted into the limiting hole 11 for limitation, so that it is kept at the adjusted length, which improves the stability of the adjustment.

[0020] The bottom of the inner cavity of the regulating box 1 is fixedly connected to the guide rail 12, and the bottom of the toothed plate 603 is fixedly connected to the guide block 13. The outer surface of the guide block 13 is slidably connected to the inner surface of the guide rail 12. The guide rail 12 and the guide block 13 can support the toothed plate 603 and make it more stable when moving.

[0021] It is worth noting that the technical features such as motor 3 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, control method and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0022] Working principle: First, the user picks up the device using handle 2. Then, the user turns on motor 3 to drive the cutting blade 5 to rotate for cutting. Next, the user turns handle 604, which drives transmission rod 601 and gear 602 to rotate. Gear 602 drives toothed plate 603 to move, which in turn drives connecting plate 14, motor 3, and cutting blade 5 to move. The length of the device can be adjusted, allowing the cutting blade 5 and motor 3 to be inserted directly into narrow spaces for cutting. Before adjusting the length, the user pulls slide rod 8 using handle 7 to release the limit on toothed plate 603, while simultaneously applying pressure to spring 9. When the adjustment is complete, the pressure on the spring 9 is released, and the elasticity of the spring 9 drives the slide rod 8 to be inserted into the limiting hole 11 for limiting, keeping it at the adjustment length and improving the stability of the adjustment. When the cutting disc 5 is damaged, the user can use a tool to turn the bolt 403 in the threaded hole 402 to remove the fixing of the cutting disc 5 and remove it. Then, the new cutting disc 5 is placed on the mounting plate 401 through the mounting port 10, and the cutting disc 5 is fixed and installed by turning the bolt 403 in the threaded hole 402. This makes it convenient to install the cutting disc 5 and reduces the time for replacing the cutting disc 5.
